With no HDD, the NVR would normally be beeping periodically.
Check the web GUI under Events and see if alarm under HDD Exception is enabled.

If it is, disable it and see if the sound stops.
If it is not, enable it and confirm the alarm is a loud beep and not a ticking noise.

Oh - I thought the problem you were having was it was making the ticking noise.

Same here! That's not normal, IMO.

If there was a hard drive or fan somewhere that had already been excluded, my next guess would be that the power supply is "crowbarring" (clamping voltage output to limit current when its output is too high OR overloaded).

It would do this if something under the PC board is shorting a power rail to the case; could be a board standoff missing, a misplaced or a loose screw, nut, etc. slipped under the PC board and shorted metal case to a PC board power rail.

I've also heard a failing filter capacitor click on a switching-type power supply such as this; don't recall ever hearing any linear power supplies click.

What "screen" are you referring to?
